Subject: [patch 30/78] kasan, arm64: rename kasan_init_tags and mark as __init
Date: Fri, 18 Dec 2020 14:03:03 -0800	[thread overview]
Message-ID: <20201218220303.pv_SIRaL7%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201218140046.497484741326828e5b5d46ec@linux-foundation.org>

From: Andrey Konovalov <andreyknvl@google.com>
Subject: kasan, arm64: rename kasan_init_tags and mark as __init

Rename kasan_init_tags() to kasan_init_sw_tags() as the upcoming hardware
tag-based KASAN mode will have its own initialization routine.  Also
similarly to kasan_init() mark kasan_init_tags() as __init.
